[Scientific American] …the sustainability think tank Pacific Institute, in a report released on June 21 on water issues of fracking, says fracking’s water woes aren’t confined to just the precise chemicals involved but extend to ensuring wells don’t permit aquifer contamination or whether freshwater is plentiful enough to support the industrial process. There are also the human health and environmental concerns about wastewater spills.
Then there’s the hundreds of millions of gallons of wastewater. The most common means of disposal—pumping the water underground—can cause earthquakes by raising the subsurface pressure—a greater risk than that from fracking in the first place.
The report, which Pacific Institute hopes will separate “the frack from the fiction,” also finds looming conflicts—and in some cases already existing battles—over water use for fracking and water use for agriculture…
